Life on his own had become, he realized then, untenable. He had had enough of solitary walks home at the end of desultory parties; of entire Sundays passed without speaking a word to another human; of holidays spent tagging along with harassed couples whose children left them no energy for conversation; of the knowledge that he occupied no important place in anyone’s heart. He loves Kirsten deeply, but he hates the idea of being on his own with almost equal force.
